Heart murmur

Heart murmurs are sounds in the heart caused by turbulent bloodflow. The sounds are often described as a whooshing or swishing noise, and can be heard when a doctor is checking your heart with a stethoscope. Although some heart murmurs are innocent, others could be a sign of heart disease. Health care providers can check the heart and create a treatment plan once they determine the cause of the murmur.

• Chest pain
• Persistent cough
• Swollen neck veins
• Dizziness and fainting
• Blue or gray coloring of the fingernails or lips
• Lack of growth in infants

Innocent murmurs can be caused by a number of common factors.

• Anemia
• Exercise that increases heart rate
• Fever
• Growth spurts
• Hyperthyroidism
• Pregnancy

More serious heart murmurs are often due to congenital conditions or acquired through heart damage or disease that occurs in adulthood.

• Calcium deposits
• Cardiac shunts
• Endocarditis (infection of the heart’s inner lining and valves)
• Holes found in the heart
• Rheumatic fever

• Diastolic murmurs occur when the heart is filling with blood.
• Systolic murmurs happen when the heart is emptying.
• A continuous murmur is present throughout the entire heartbeat.

• Anemia
• Autoimmune disorders
• Family history
• Heart disease
• Overactive thyroid
• Pulmonary hypertension (high blood pressure in the lungs)

Murmurs in children often go away over time, but there is no specific form of prevention for congenital or acquired heart murmurs. Living a healthy lifestyle helps prevent conditions that can lead to heart murmurs in yourself and your children.

Innocent heart murmurs do not require treatment. However, a worrisome heart murmur needs close monitoring by a cardiologist. Medication or surgery may be needed.

• Medications used to treat heart murmurs:
  • Blood thinners
  • Water pills
  • Angiotensin-converting enzyme (ACE) inhibitors
  • Beta blockers
• Heart valve repairs are used to treat heart murmurs and can be done as:
  • Open-heart surgery
  • Minimally invasive heart surgery
  • Robotic heart surgery
  • Catheter procedure
